Pre-impregnated materials (prepregs) are reinforcement fibres or fabrics into which a pre-catalysed resin system has been impregnated by a machine. The resin systems in these materials react only very slowly at room temperature, giving rise to working times of many days to several months. The prepreg resins can only be fully cured by heating them to the prescribed cure temperature.

Coating that can be applied to any prepreg for excellent handling and mould conformance even at 35°C
Extremely low void content in any thickness with de-bulk
Cure cycles can be optimised to use infusion grade tooling
